Owner`s manual

Complete installing the coaxial cables connected as shown in Figure 12, depending upon the options

you have in your K3. Note that:

1. The cables shown in gray do not change. They are shown in case one becomes disconnected from

the KREF3 board while you are working.

2. If you do not have the KRX3 subreceiver installed, only one coaxial cable is used to connect J2

on the KREF3 board to J83 on the main KSYN3A board.

3. If you have the K144XV 2-meter option with the reference oscillator phase lock option installed,

you now have only one coaxial cable instead of two cables as before. If you removed the

K144XV top cover to disconnect the other coaxial cables from the K144XV module, do not plug

the cable into

REF IN until you are instructed to replace the module in the following steps. That

cable must pass through a hole in the K144XV top cover.

4. No connection is made to the large connector at the top of the new KSYN3A board(s). This

connector is for future use.
